In concrete industry, the use of concrete solid wastes is becoming further common since it can minimize associated costs and environmental implications. The current research looks at how concrete performs when polypropylene (PP) plastic, produced from pollution garbage items, is used as a partially...

This research focuses on hydrothermal gasification (HTG) and hydrothermal liquefaction (HTL) studies to produce bio-hydrogen from domestic mixed waste. HTG and HTL studies were studied at temperatures of 300–450°C and 300–400°C, correspondingly, with a catalyst level of 6 wt %. The sol-gel technique...

Recycling of wastewater is an important issue as it is used for many important applications such as industries, agriculture, household applications and due to water scarcity across the different countries. Wastewater treatment is an important activity as it protects human being and the ecosystem...

The coronavirus (COVID-19) is a threat to public health and caused several social, environmental, and economic problems. During the lockdown in different countries, waste generation has been significantly increased due to the high consumption of packaged food and increase the order of food via...

Urban household waste causes serious pollution of the urban ecological environment. Waste separation and processing is an effective approach to reduce the ecological environment damage caused by household waste. From the perspective of the source of urban household waste separation, this paper...

Waste management is one of the most crucial part of the sustainability concept. In Turkey, waste management of the small household appliances under waste of electrical and electronic equipment (WEEE) category still remains as an issue to handle although its production is very large and long...

To assess the indoor air quality an investigation was conducted in Lucknow from November 2014 to October 2015. In total seven pollutants viz. SO2, NO2, CO2, CO, NH3, H2S, PM10 and PM2.5 were assessed in five urban and five rural houses. House selection was done after questionnaire survey with...

The purpose of this paper is the presentation of the results compiled from self weighing of household food waste and self filling of waste collection diaries that took place in Greece. A diary was compiled and given to 101 urban households in various areas of the country. The participants were asked...

Two identical four air-cathode single chamber membrane-less microbial fuel cells were stacked and tested under in series and in parallel electrical configurations. Fermentable household waste extract (FORBI; 0.8 g COD/L) was used as substrate, in all cases. Linear Sweep Voltammetry (LSV) was carried...

Due to the pressing necessity of switching to alternative sources of energy, fuel cells (FC) for household applications have emerged as an alternative for decentralized energy supply. Despite the advancement on technological developments, concerns on the availability of critical raw materials...

Re-Tek UK and its partners, Enscape Consulting and the University of West of Scotland commenced trials for the collection and recovery of critical raw materials from waste electrical and electronic (WEEE) products in July 2016. Sponsored by the EU LIFE funded project ‘Critical Raw Material Closed...

This research work focuses on the analysis of the involved uncertainty and the corresponding reliability in the sizing of rainwater harvesting systems. For this reason, an uncertainty analysis was carried out, based on 23 years of historic daily record of a station in Kimolos Island (Aegean, Greece)...

With increased contribution of household and kitchen wastes in overall MSW and its preferred conversion by biomethanation there is a need to study decomposition rates and kinetics, ‘leachate potential’ and related issues– especially to promote decentralized treatment. Anaerobic digestion...

The technology transfer for rural livelihood development had greater impact to protect microclimatic conditions which further affects the microflora and microbial activities to larger extent in the Indian Himalayan Region (IHR). The technological interventions were made by the Himalayan Research...

The effects of various socioeconomic characteristics on Willingness-to-Pay (WTP) values for service attributes of Solid Waste Management (SWM) were evaluated in this study. The Stated Choice (SC) data collected from respondents in the Kolkata Municipal Corporation (KMC) area, India were analyzed...

The study examined the willingness of rural households to pay for sustainable management of community forests in Southwest Nigeria. The value elicitation format used was the dichotomous choice contingent valuation technique. The multistage random sampling technique was used in selecting 180 rural...

This paper is focussed on the study of the air movement and temperature distribution inside refrigerating compartment of household frost-free refrigerators. It is well known that the correct air circulation and temperature distribution inside the refrigerated chamber are two of the most important...

Effective eco-environment rehabilitation is an essential policy issue in arid oasis ecosystem. Since 2007, a policy which focuses on environment restoration and protection was implemented in the Shiyang River Basin of Gansu Province, China. Using Minqin oasis as a case, the effectiveness of policy...

Polybrominated diphenyl ethers (PBDEs) are a class of widely used flame retardants that are incorporated into a wide range of consumer products such as household appliances, plastics, textiles and computers, to prevent fire. They were first introduced in the environment in the 1970s and their...

Undoubtedly, sun is the cleanest energy source. Specific systems are needed however for the collection and transformation of solar energy and the manufacturing processes of such systems, as well as the production of the raw materials required, are associated with impacts to the environment. As a...
